VENTILATOR HOOD
HOOD SECTION - ANSUL® FIRE SUPPRESSION SYSTEM
13
IMPORTANT:
All servicing of the fire
suppression system to be
performed by an
authorized Ansul® agent
only.
1. Actuation of the Ansul® system will cause the pressure cartridge seal
to be punctured, which will pressurize the 1.5 gallon media tank. Fire
suppression media will be forced through the piping where it will spray
from the various nozzles.
2. The cooking appliance surface is protected by two type 290 nozzles.
3. The plenum area between the filters and the fan is protected by a
single type 1W nozzle.
4. The pressure integrity of the plenum bulkheads is maintained by the
use of compression fittings at the piping penetrations.
5. Nozzles are protected from grease contamination by press-on silicone
rubber caps.
